Hand Blown Glass Art

I want to paint the outside of glass ornaments and don’t know if i can use acrylic paint.

I found some really neat oldies in an estate. But they were stored in a shed and have powder mold on them, from this damp OR Coast climate. Any ideas how to safely remove this from the glass ornies? These are old German thin glass ornaments. Maybe there’s no helping them? Any ideas?

I want to do a craft with square glass ornaments. Is there a website I can find them on?
